This study evaluated the properties of bio-coal briquettes made by blending coal with beniseed (sesame seed) stalks in order to determine the optimum composition. The briquettes were produced using a hydraulic compression machine at 5, 10 and 15 bar applied to coal:biomass compositions of 100:0, 80:20, 60:40, 40:60, 20:80 and 0:100% by weight of mixture and particle sizes of 212, 300 and 600 µm. The physical, ultimate and proximate properties of the briquettes were then measured and analyzed. The results indicated that the optimum composition for producing the briquettes lies between 60:40% and 40:60%. These ranges of composition of briquettes had the lowest ignition time of 57.6s, highest percentage volatile matter of 42.7% and low percentage sulphur content of 0.38%. Furthermore, the 40:60% briquettes had the highest mean calorific value of 26.67 MJ/kg. These indicate good potentials for briquettes using coal and beniseed stalks as an alternative energy source while contributing to a friendly environment and wealth generation.

Biogas can be an important alternative energy source for the sustainable development of the energy sector. To understand the performance of the family-size biodigester in Bangladesh, a household level survey on randomly selected 360 biodigester adopters was conducted. It is evident from the study that adoption of biodigester at the household level is economically and environmentally viable. Most of the biodigesters were constructed for single household and production of biogas was sufficient for cooking for single household. About 35% of biodigesters generated surplus gas from which they earned money by selling the surplus gas. About 91% of the biodigesters were feed with cow dung, one of the optimal biogases producing substrates, which has easy access in their own households. The factor analysis suggests that the most important factors to make biodigester economically viable are: capacity of biodigester, availability of substrates, amount of investment for biodigester, and economic benefits derived from biodigester.

Biomass energy accounts for more than 92 percent of overall energy consumption in Ethiopia. As a result, Ethiopia is one of the world’s most biomass-dependent countries. The high reliance on wood fuels and agricultural residues for fuel harms society’s social, economic, and environmental well-being. This study aims to create and test the quality of fuel briquettes made from the coffee husk. Also built and produced are a carboniser/charcoal kiln, a manually operated molder system, and a briquette stove for burning the manufactured briquette. The carboniser converts 15 kg of raw coffee husk into 6 kg of carbonised char in 25 minutes, and the manually operated briquette molder can press 30 kg per hour. The efficiency of converting raw coffee husk into carbonised char content was 40.12%. In the geological survey of Ethiopia, the geochemical laboratory directorate received triplicate samples of the fuel briquette charcoal for analysis. Moisture content, fixed carbon content, ash content, sulfur content, and calorific value were determined using a bomb calorimeter and a ceramic lining furnace. Physical properties of fuel briquettes ranged from 10.03% moisture content, 970 kg/m3 density, 81% fixed carbon, 5.15% ash content, 0% sulfur, and 30.54 Kcal/kg higher heating value, according to laboratory results. The results of the study revealed that the coffee husk fuel briquettes produced have more positive characteristics. Fuel briquettes were cost-effective and environmentally friendly and reduced deforestation compared to firewood. This study clearly shows that briquettes made from coffee husk could be used as an alternative energy source when this kind of waste is well managed.
